Working for Berlin

IBB is a reliable, strong partner for Berlin and its business community. For us, 'Working for Berlin' means providing optimum support for Berlin-based businesses through tailored financing. IBB's business development activities are geared primarily towards loan-based and investment-orientated forms of finance which are offered as revolving support funds. Subsidies supplement the product range, especially when it comes to technology and investment support funding. Comprehensive financing consultancy rounds off the portfolio of services offered.

Focus on technology SMEs

When it comes to financing for SMEs, IBB places special emphasis on small and medium-sized enterprises operating in Berlin's clusters, i.e.
